Multi-hole cable tray model and specification table

Multi-hole (perforated) cable trays are available in various heights, widths, and materials, with detailed load capacities and span specifications for industrial and commercial applications.OverviewMulti-hole cable trays, also known as perforated or vented trays, are designed to support power, control, and instrumentation cables while allowing ventilation to prevent heat buildup. They are commonly used in environments where airflow, weight reduction, and cable management flexibility are important. These trays are typically made from steel or aluminum and may have galvanized, painted, or powder-coated finishes for corrosion resistance .Key Models and TypesHusky Ladder Tray: Two longitudinal side members connected by rungs; suitable for heavy loads and long spans. Available in I-Beam, Flange-In, and Flange-Out designs .Husky Trough Tray: Solid or ventilated bottom with corrugated or flat pan design; ideal for control and instrumentation cables .Husky Channel Tray: One-piece support with solid or ventilated bottom; used for power, control, or signal cables .Husky Wire Basket Tray: Wire mesh design for data communication and fiber optic cables; highly flexible and easy to fabricate on-site .Specification Table (Representative)Tray TypeHeight (in)Width (in)Load Capacity (lbs/ft)Span (ft)MaterialFinishLadder I-Beam3.5 – 7.03.5 – 12.050 – 100+8 – 24Steel/AluminumHDG, Mill, PaintedLadder Flange-In3.5 – 6.03.5 – 12.050 – 100+8 – 24Steel/AluminumHDG, Mill, PaintedTrough Ventilated4.0 – 6.04.0 – 12.050 – 100+8 – 24Steel/AluminumHDG, Mill, PaintedChannel Solid/Vent3.5 – 6.253.5 – 10.050 – 100+8 – 20Steel/AluminumHDG, Mill, PaintedWire Basket2" x 2" mesh4 – 12Light to Medium6 – 12SteelPaintedNotes:Load capacities and spans vary depending on tray height, width, and material; always refer to manufacturer load tables for exact values .Multi-hole trays allow ventilation, reducing heat accumulation for sensitive cables.Compliance with NEMA Class 8B, UL, and other standards ensures safety and reliability .Selection ConsiderationsCable Type: Power, control, or data cables may require different tray types.Load Requirements: Determine maximum cable weight and select tray height and width accordingly.Span and Support: Ensure proper support spacing to prevent sagging.Environmental Conditions: Choose material and finish based on indoor/outdoor use, humidity, or corrosive environments.Installation Flexibility: Wire basket trays allow easier field modifications, while ladder and trough trays provide higher load capacity .
